CANOGA PARK, Calif., Nov. 13, 2012 /PRNewswire/ --The Environmental Security
Technology Certification Program (ESTCP) office of the U.S. Department of
Defense (DoD) has awarded Pratt & Whitney Rocketdyne approximately $2.3
million to design and develop a 200-kilowatt high-concentration photovoltaic
(HCPV) solar-power field on one acre at Edwards Air Force Base in California.
The project is designed to demonstrate the high-performance and
cost-effectiveness of HCPV technology for use at DoD installations, and
ultimately large utilities and other industrial applications. Pratt & Whitney
Rocketdyne is a United Technologies Corp. (NYSE: UTX).

"We're honored the Department of Defense has chosen Pratt & Whitney Rocketdyne
to further demonstrate this revolutionary technology, which provides clean
energy and shines a light on greater energy independence and energy security,"
said Neeta Patel, director, Energy Systems, Pratt & Whitney Rocketdyne.

The solar field will include a dozen commercial-scale dual-axis HCPV units
that track the sun from sunrise to sunset, feeding the electrical grid rather
than relying on the local utility company. Each unit contains about 60 square
meters of the HCPV modules, manufactured by Semprius, Inc., of Durham NC. The
modules have a concentration ratio of 1,111 suns. The project will also
include a 200-kilowatt lithium-ion battery unit. As part of the contract
award, Pratt & Whitney Rocketdyne will perform field layout, systems
integration, energy storage integration, and lead development and test of the
HCPV/storage hardware, using cost and performance-optimization models already
proven on the International Space Station and in smaller technology
demonstrations at the University of Alabama-Huntsville.

Pratt & Whitney Rocketdyne, a part of Pratt & Whitney, is a preferred provider
of high-value propulsion, power, energy and innovative system solutions used
in a wide variety of government and commercial applications, including engines
for launch vehicles, missile defense systems and advanced hypersonic engines.
